Multidimensional β-diversity responses to global change: a meta-analysis highlighting divergent effects on plant communities.

ABSTRACT: In the Anthropocene, global change is reshaping biological communities, potentially leading to widespread biotic homogenization-a worrying erosion of biological distinctiveness. However, the extent to which human activities have homogenized plant communities worldwide remains a pivotal unresolved question. To address this gap, we conduct a global meta-analysis of 1604 experimental and observational comparisons from 256 studies to assess the impacts of major global change drivers on plant β-diversity across its taxonomic, functional, and phylogenetic dimensions. The findings indicate no significant net change in plant β-diversity globally, with responses varying markedly across global change factor types, biogeographic regions, ecosystems, and plant life forms. Specifically, climate change
